Raj: Oh, this is amazing. I wish I had a playhouse like this when I was a kid.
Penny: Really? You never had a playhouse?
Raj: No. I mean, my dad did buy the house next door for us to play in.

Howard: I'm gonna hook up the garden hose, so it has running water.
Amy: Why does it need running water?
Howard: Same reason it's got electricity: Bernadette and I both work, and we're overcompensating.

Sheldon: This reminds me of a traditional Amish barn raising. With everyone pitching in.
Howard: How exactly are you pitching in?
Sheldon: I don't hear anyone else giving facts about traditional Amish barn raising.
Leonard: The rest of us are pitching in with hammers and nails.
Sheldon: Well, facts are my nails, and my voice is the hammer which pounds them through the wood of your skull.
Penny: Well, that is how it feels.

Raj: Hey, uh, can you pass me that drill?
Sheldon: Yeah, fun fact about Amish barn raising, they don't use any power tools.
Penny: Amy, make him stop.
Amy: No. If he tires himself out now, he'll sleep better tonight.

Bernadette: Hey, Howie, can you give me a hand? I need to get some work done, and the kids are climbing all over me.
Raj: You know what? I'll watch them.
Bernadette: You sure?
Sheldon: But I was just about to tell everyone why they're called Pennsylvania Dutch when they really hail from Germany.
Raj: Yep.

Howard: So, what do you think? Pretty cool, huh? And when our kids outgrow it, we can Airbnb it to other people's babies.
Bernadette: Funny.
Howard: You all right? Sorry, I haven't had a second to myself. So let me just go back inside, finish my report, brush my teeth, change out of my pajamas, make a sandwich, and then I'll come out here and laugh at your joke.
Howard: Ooh. As long as you're making sandwiches- You can laugh at that one later, too.

Sheldon: All right, I've kept you in suspense long enough. "Dutch" is a bastardization of the word "Deutsch," meaning German.
Penny: What's German for "annoying"?
Sheldon: Nervig. Why do you ask?

Raj: Sheldon, you sure you're ready for this? This movie's pretty scary.
Sheldon: Please. I'm an adult. I think I can handle it.
Leonard: That's what you said about the butterfly pavilion at the zoo.
Sheldon: That was my fault. After I pet that goat, I felt like a gladiator.

Amy: What do you guys think you're doing?
Raj: We're showing Sheldon Halloween.
Amy: Absolutely not. Sheldon, come home.
Sheldon: But I really want to watch it.
Amy: I know you do, but I am forbidding it.
Sheldon: Oh, man. Sorry, guys.
[in the hallway:]
Sheldon: What took you so long?
Amy: I'm sorry. I just got your text!

Sheldon: Hello, Bernadette.
Bernadette: Wait, did you just walk into my house?
Sheldon: No, Howard let me in.
Bernadette: Where is he?
Sheldon: Oh, he got in his car and drove away.

Sheldon: Oh. Is that watermelon for anybody?
Bernadette: It's for Halley.
Sheldon: Is she gonna eat all of it? God, no wonder she looks like Churchill.

Bernadette: What do you want, Sheldon?
Sheldon: Howard said your feelings were hurt.
Bernadette: Well, Howard's wrong. I don't care if someone makes fun of me.
Sheldon: All right. Apparently I came all this way for nothing. Unless Halley wants to share that watermelon?

Bernadette: You think Amy's the first person to make fun of me for having a squeaky voice? Do you?
Sheldon: I feel like my chance at watermelon is dangling by a thread.

Bernadette: She's not. It's been happening my whole life. And-and she called me out for being mean? Well, I've had to be mean. It's hard to be taken seriously when you're always the smallest person in the room.
Sheldon: I know that. I was in high school when I was nine years old. I tried to tell the other kids that although my physical stature was small, my intellectual stature towered over them. That only seemed to make things worse.

Bernadette: The kids called me Bernadette the marionette.
Sheldon: (laughs) Because you're small. That's funny.
Bernadette: No, it's not.
